hadoop 运行java 清洗数据 报错Failed to set permissions of path: \tmp\...

清洗数据写好代码后，运行报错：

ERROR org.apache.hadoop.mapred.TaskTracker: Can not start task tracker because java.io.IOException: Failed to set permissions of path: \tmp\hadoop-****** to 0700

eclipse运行作业  Failed to set permissions of path: \tmp\hadoop-admin\mapred\staging\Administrator-1506477061\.staging to 0700：Windows环境下的Hadoop TaskTracker无法正常启动  包括0.20.204、0.20.205、1.0.0版本

很多人采用修改FileUtil类 checkReturnValue方法代码，重新编译，替换原来的hadoop-core-1.0.0.jar文件，来解决。

private static void checkReturnValue(boolean rv, File p,FsPermission permission
 ) throws IOException {
    if (!rv) {
    throw new IOException("Failed to set permissions of path: " + p +
 " to " +
 String.format("%04o", permission.toShort()));
    }
}

我自己没有编译直接从网上下载个编译好的：
